Patented Dec. 2?, 1910.

Application filed September 13, 1910. Serial No. 581,767.

To all whom it may concern:

hingedly connected to the bottom of the eas- Be it known that 1, Joan A. PARKER, a ing near its large end and is adapted to be citizen of the United States, residing at Gardiner, in the county of Kennebec and State of Maine, have invented a new and useful Graphoscope, of which the following is a specification.

This invention relates to graphoscopes particularly designed for use in viewing picture postal cards, and one of its objects is to provide means whereby light rays may be deflected into the graphoscope and onto the picture contained therein.

A further object is to provide means whereby lights of different colors may be directed upon the picture.

A still further objectis to provide a graphoscope which is simple in construction and can be readily manipulated.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of the claims without cleparting from the spirit of the invention.

In the accompanying drawings the preferred form. of the invention has been shown.

In said drawings,Figure1 is a. plan view of the device, a portion thereof being broken away. Fig. 2 is a vertical. longitudinal section therethrough.

Referring to the figures by characters of reference 1 designates a casing preferably in the form of an elongated pyramid frustum this casing being open at its large end and having a large opening 2 in the top thereof at the small end of the casing. Supporting cleats 3 are arranged along the sides of the opening 2 and are adapted to support glass lights l of different colors. A backing plate or closure 5 is hingedly connected to the top of the casing 1 at one end of the opening 2 and carries a mirror 6 which may be supported at a desired angle relative to the casing, by means of a chain '7 or the like. This mirror is adapted to be held at such an angle as to deflect the rays of light through the opening 2 and onto a postal card such as indicated at A and which is located in the small end of the casing 1. A magnifying lens 8 is secured within the casing 1 and a supporting member 9 is held at a predetermined angle to the casing, by means of a chain 10, and a rod 9, or any other suitable connection. A handle 11 may be attached to the top of the casing so to enable the device to be conveniently car= ried.

In using the graphoscope the card A to be used is placed in the casing 1 through the opening 2 and each of the cards binds against the sides of the casing so as to support the card in an upstanding position. If it is desired to View the card in natural light, the opening 2 is left uncovered. The mirror 6 is then adjusted so as to deflect the light rays onto the exposed face of the card and the card can then be viewed by looking into the large end of the casing and through the magnifying lens 8. To change the color of the picture, a glass light of the desired color is placed upon the cleat 3 so as to extend across the opening 2.

It will be seen that the device is very simple in construction and has no part which will easily get out of order. Vihen it is notin use the mirror 6 and the plate 5 can be swung downwardly into the opening 2 and the rod 9 can be moved against the bottom of the casing.

It is desirable to hold the card curved while in the casing so that all parts thereof will be in focus and clearly visible through the lens 8. This curvature of the card has been clearly indicated in Fig. 1.

What is claimed is 1. A graphoscope including a casing having a sight opening at one end, a light opening adjacent the other end of the casing, and reflector for deflecting light rays through said light opening and into the easing.

2. A graphoscope including a casing having a sight opening at one end, there being a light opening in said casing adjacent its other end, said casing constituting means for supporting a picture adjacent the light opening, a mirror adjustably connected to the casing for deflecting light rays through the light opening and upon the picture, and a magnifying lens within the casing and between the two openings.

3. A graphoscope including a casing having a sight opening at one end and a light opening adjacent its other end, said casing constituting means for holding a picture adacent the light opening, means adjustably In testimony that I claim the foregoing mounted on the casing for deflecting the as my own, I have hereto affixed my signa- 10 light rays through the light opening and ture in the presence of two Witnesses.
